To all whom it may concern Be it known that I, /VILIIELM RO'JIIE, a subject of the Emperor of Germany, re siding at Ileichenbaeh, in Silesia, in the Empire of Germany, manufacturer, have invented new and useful Improvements in and in Connection with IVaste or like Carding or Breaking Machines, of which the following is a specification.

This invention has reference to breaking or carding machines for the production of cleaning waste, but is applicable to other breaking or carding machines.

My improvements have reference in particular to the breaking or carding cylinder of such machines and to feed roller arrangements suitable for cooperating with a breaking cylinder. i

The object sought to be attained under this invention is, to keep the threads or fiber of the material acted on as long as possible and so to ultimately obtain cleaning waste with a longstaple which will lend itself to being got ready for the market in rope form. I seek to use such a combination aswill not tend to tear the material or waste acted on into short lengths as heretofore.

Under my invention I utilize a breaking cylinder of a form hereafter fully described, and I combine therewith a feed roller arrangement also hereafter fully described the combination enabling the object in view to be attained.

The drawing attached shows a diagrammatic section of the breaking cylinder and the feed roller arrangement employed by me.

In the breaking machinery at present in use and when dealing with long fibrous material, the fiber being acted on is apt to get embedded in the teeth of the breaking or carding cylinder, and is not so efliciently treated, the material having a tendency to become wrapped around the cylinder and to sink downward toward the root of the teeth and the cylinder face. This I propose to prevent by leaving spaces or widths a, 7) of the cylinder face void of teeth or spikes. I therefore arrange to have any suitable number of ranks of teeth 0 arranged across the cylinder alternately with open spaces of cylinder surface such as the spaces a, Z),- or I may leave open spaces at any desired intervals and even irregular intervals, and the size of said spaces may vary too, In

Specification of Letters Patent.

*atented May 19, 1914. Serial No. 766,605.

order to still :turther check the fibrous material from getting bedded too closely down in the cylinder teeth and against the cylinder face (Z, I attach lags or battens c of wood or other material at intervals running lengthwise of the cylinder or spirally or otherwise arranged. Such lags of wood may be of a thickness about equal to the depth of the teeth, or a little more, and occur at one, two, or more intervals around the circumtierence of the cylinder. The drawing shows the application of four such lags e at regular intervals and the use of such lags is of great importance. By their use, fibrous material of any length lying on and clinging to the cylinder must naturally pass thercove' and cannot sink to the cylinder surface at that point. Thus, other spiked 0r toothed rolls, such as combined rollers and elearcrs and doifer, can more readily take off or work such material because some portion of the material is diverted into or to ard the path of the working teeth on the other rolls &c. Such diverting lags or battens may be used upon cylinders having the teeth disposed in any known or approved way. The lags 0 shown. run parallel one to the other.

In feeding such breaking or carding cylinders the present feed rollers (which are spiked ones) have likewise the tendency to choke or have their teeth embedded in fiber which becomes wrapped or compacted around the rollers thus interfering with the feeding or working of the machine. I therefore use a lower spiked, or toothed, or fluted or like roller f mounted near the feed table or other feed device such as the feed lattice g, and, above this, I mount a plain iron or other smooth roller 7t which forms the upper roller of the pair. Above this, I mount a larger smooth iron roller 2' the two smooth rollers h, i revolving in the same direction. The result of such a combinat-ion is, that fibrous material is not so readily carried around and cannot become embedded upon such rollers. The upper and larger smooth roller 7: tends to clear the lower roller 7b and directs material back to the main breaking cylinder A. Just above the large smooth roller I form a trough or deposit chamber 7" by means of a flange j on the casing, or by a part applied to the casing, or in other manner. In this trough or chamber 7' dust and grit is deposited when the machine is at work,

which dust falls or is spread over the large upper roller and serves to wipe, push back, or brush oil any fibrous material tending to pass to or around the upper roller. By the above described roller arrangement I facilitate removal of such fibrous material and the passing of the same back to the revolving breaking or carding cylinder at work.

The gist of my invent-ion lies in the use of smooth or blank rotating rollers in manner described and the combination of a rotating breaking cylinder partly void of teeth and having attached battens so arranged or combined that the fibrous ma terial is not so liable to become embedded in the breaking or carding teeth of the same as to detriment-ally affect the Working of the breaking machine.

I declare that what I claim is- 1. A waste carding machine having a feed device consisting of a lattice, a lower toothed roller, a superposed smooth upper roller and a larger upper roller, said rollers cooperating with a mainrevolving breaking cylinder partly void of teeth said main cylinder having applied lags.

2. A waste carding machine comprising feed devices including a lattice, a toothed roller, and superposed rollers, and a main revolving cylinder acting along with the feed devices, said main cylinder being void of teeth over spaces and having lags applied to the cylinder in the spaces void of teeth as described.

3. In a waste carding machine, a lattice, feed roller devices, and a revoluble main breaking cylinder, void spaces on said cylinder, lags fixed in said spaces and secured to the cylinder periphery as set forth.

4. A waste carding machine comprising a main revolving cylinder and feed mechanism consisting of a toothed roller, a first smooth roller and a larger smooth roller, a covering inclosing the smooth rollers and a trough or pocket y" inside, the covering and as set "forth.

5. A waste carding machine comprising a main revolving cylinder, blank spaces on the cylinder and lags applied in the spaces, and a feed device cooperating with the cylinder consisting of a lattice, a spiked roller an upper smooth roller, and a larger superposed smooth roller thereabove and a casing covering the smooth rollers and a dust and grit pocket 7" combined with the casing, all as set forth.

In testimony whereof I have signed my name to this specification in the presence. of

two subscribing witnesses.
